I painfully managed to passthrough my Intel HD Graphics 4600 (Haswell), but I can't get HDMI audio to work

Software & Operating Systems VFIO

The driver is installed and all, but I get no audio device.

I did passthrough both devices. The IGD itself and its HDMI audio device:

00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)
00:03.0 Audio device: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller (rev 06)

Any ideas?

Sorry, I don’t know how to help. Just pushing this back to the top of the feed hoping someone has an answer.

you probably have already checked but just to cover basics

have you changed your Default audio device to HDMI audio in windows and volume is up and not muted in both software and monitor/tv?
